Recently, some people have discussed about the power consumption of our nova ips screen in different background colour.
Here is a simple test to check out the real situation.
Again, the test is conducted with a power meter. The phone is initially charged to 100%. Hence, the reading is approximately to the power consumption of the phone.:laugh:
Firstly, the screen was set to 100% brightness. Here is the power consumption of the screen in different display colour.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then, the screen was set to 0% brightness.
As you can see, the power consumption are nearly the same with the same brightness level. Even thought the black is consuming little bit less power, the difference is negligible. The major factor affecting the consumption of the screen is the brightness.
Hence, we can use any background we like, no matter what colour it is. :laugh:
ps. the reading of the meter is not the actual power of the phone. This is due to some power loss during the voltage transformation. However, the value is still comparable and the test is a reliable test. :laugh:
Just type the thanks button if u think this is helpful.:laugh:
well, that's some good research.
Thanks for you time, good job. :good:
Indeed, it's very helpful, more for the devs I think...
However, can ask you to make test with different clockspeeds and voltages? like using zeus at 200Mhz with -7v->0v->+7v, then something like 600Mhz with -7v->0v->+7v and then 1200Mhz~1300Mhz with -7v->0v->+7v
Those values can give a more widely view and maybe help to something like SODs maybe? we know if voltage goes too low it wont even awake phone, so that could help to determine a min value for that, and a max value to not burn the core

I used "watts" to keep track of my battery, just started using it yesterday and today I saw a weird period of the graph where the battery actually raised up to 3% higher by itself. Is this normal? Have a look at the graph below.

Maybe you had your phone connected to the computer at that point?
No, it was in my pocket. I can be sure about that.
Well its probably measuring voltage.
Voltage goes up when the battery gets warm.
Voltage goes up when the current goes down.

I thought it was the other way around? Voltage goes up when the battery gets colder...
yeahh you're right thats why you can put your batteries in the fridge to make them work again . lol i discovered this when i was 5 XDXD

Resistance goes down with cold, so if your measuring a circuit there would be less voltage drop giving the appearance of higher voltage provided the voltage source is not subject to the same temprature fluctuations.
I've just checked Watts data for the last couple of days on my phone -- there are those spikes too. It must have something to do with hot/cold issue as mentioned by others.

Is this good battery life?
No backgroud apps.
Power saving mode.
Lowest brightness.
11 minutes Wi-Fi.

no good for me. maybe your juice plotter is drinking up your juice. try uninstalling it and see if there is a significant difference or try getting into setting in application and then manage application then select running application see if there is some rogue app there running that you don't use and force stop them just beware to force stop running system apps then charge your battery at full and see how much it drain. you may clear up your dalvik cache and battery stats first if you have that option.
That battery life is horrible. I regularly get > 24 hours with medium usage. There are many threads around here on improving battery life.
Yes. Absolutely terrible. Do you remember what you were doing about 7:45, when it started to tank? The temperature seems a little high to me, too.

Hello! Yesterday i downloaded Gsam APP to see my battery life and how long it lasts. My results were really bad. The consumption was around 7-8% hour, and I use the phone way more than yesterday..
Those are the screenshots of gsam:

}
Is there any solution? I really need this battery to last way more than this.
My moto x is not rooted, should I root it? My version is 4.4.3.
Cheers
First, I noticed the moto x drains real good when on calls, more than my N5. So you need to keep in mind according to gsam, 25 percent of your battery drain was the phone calls. That's huge!
Also, you have almost 3 hours of held awake time....and I'm pretty sure if you click the drop down in gsam app screen, you can't check the held awake time or times waking device, cause you're not rooted.
And, you have Bluetooth on the entire time, and location services and Google now I'm betting? Those will take a chuck of battery life also.
Lastly, 22 percent of your drain was screen. Auto brightness? Were you in bright areas a lot? When the screen is bright, it will drain fast too.
So, all that said....I'd say your battery times are about right. Getting better times will take some tweaking and sacrifice of conveniences.....and getting used to toggling features on and off....instead of always on.
Check out post number 2 in this thread....its our battery life help thread now in the N5 section. But pretty much all the info in post number 2 applies to about any device.
http://forum.xda-developers.com/showthread.php?t=2785128
Of course, you're going to be limited by not being rooted....so some things you can't do....but most you can. Or at least you can read up about it.
Good luck!
I'm new to this device and a little dismayed at the poor battery performance.
I don't consider myself a heavy user but find the battery is almost depleted after 8 hours of so, after being charged.
I can't find a SCREEN ON TIME in the settings so not sure how much screen time I'm getting.
I have received the September update, shortly after getting the phone.
Do any of the custom ROMs offer better battery life?
thanks
If you went into settings>battery it should be there

You also suffer the max frequency bug if seems

Doesn't seem so, all cores on the lowest frequency
Hello everyone, today I woke-up with my phone pretty much dead, with only 1% of battery. The weird thing is that before bed, the battery percentage was around 70ish percent.
Here's a screenshot of the battery usage:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Some details to help me figure it out the issue:
Auto optimize daily is on.
Auto restart at set times is on (it restarted around the time that the battery percentage drops to the floor).
Adaptative power saving is off.
Background usage limits is configured properly.
Any help will be appreciated, thanks in advance!
it's possible the Google services was running (updates and such) and used up a lot of the battery. Google being the OS developer tends to run quite a lot of things in the back without users knowing, and this is quite normal. As to draining such large amount, is your location in a poor data coverage area? if you are, then the phone likely was using extra battery to strengthen the signal. Note that even with wifi connection, data is still used for some activities by the phone.
if this keeps persisting then Google is probably not the culprit and you'll want to report the issue right away to samsung using samsung members app > get help > error report. just be sure to see the drain and immediately report.
Also, I've seen some users install 3rd party apps to track in finer detail on what is using the battery the most. I myself do not know as I don't use it, but you can easily find some recommendations on Reddit i think.
